Kelly if I may make a suggestion after you are done with the 9 groups, why not break down the winner's into say two groups(one of the winner of groups 1-5 and one of groups 6-9. Then have a finals between the two winners.
Impossible!
How do you choose between at least 2 bona fide classics - Aladdin and Lion King - that are also as different as chalk and cheese.
If I was pressed, I'd place Aladdin slightly above, largely because the humour appeals to me more. However, Hunchback is a strong contender simply because it is a beautiful looking film with a solid heart.
The others are easy to rank:
4. Hercules - fun, didn't do much for me.
5. Pocohontas - nice, but takes itself too seriously.
However, where the first three rank for me will depend on mood...
